There are many posts on this and other threads over the years critical of BA's recruitment process. BA seem quite happy with it. Bottom line is simple. You don't have to join BA with it's silly recruitment processes.
It just makes one wonder why so many people spend so much time being critical of a process in a company they "choose" not to be a part of. Smacks too much of sour grapes or envy to me. If you choose not to be part of BA then why give a tinker's cuss about how they recruit?
